Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1.

The present embodiment provides a water tightness detection device that can be used to detect the water tightness of various openable sealing devices 12. The sealing device 12 may be a final product or a semi-finished product. For example, the sealing device 12 may be an electronic product, such as an electronic watch, a sports bracelet, a cell phone, and the like. In order to avoid damaging the electronic product due to the water tightness test, the semi-finished product of the electronic product (e.g., without the circuit board) may be subjected to the water tightness test.

Specifically, the water tightness detection device comprises a container 10, wherein a mixed liquid 11 is contained in the container 10, and the mixed liquid 11 comprises water and a fluorescent agent.

Before the test is performed, the sealing device 12 may be immersed in the mixed liquid 11. When the water tightness of the sealing device 12 is poor, the fluorescent agent can enter the sealed space 13 following the water.

After a certain time of immersion, the sealing device 12 can be removed. Since the fluorescent agent highlights ultraviolet rays, the sealing device 12 can be opened and ultraviolet rays are emitted from the ultraviolet light source 40 to irradiate the sealed space 13 of the sealing device 12 with ultraviolet rays during detection. When the water tightness of the sealing device 12 is poor, the fluorescent agent is attached to the surface of the sealed space 13, and the fluorescent agent is highlighted under the irradiation of ultraviolet rays, thereby displaying the water inlet area, and the size of water droplets of the sealed space 13.

In order to get rid of human factors (human observation), the visual inspection module 30 may be used to obtain a visual image of the sealed space 13 irradiated by the ultraviolet rays, and determine the water inlet area, and the size of the water droplet of the sealed space 13 according to the visual image.

It should be noted that the visual inspection technology is a mature existing technology, and can automatically perform analysis according to a visual image. In this embodiment, by using the visual detection technology, the water inlet area, and the size of the water droplet of the sealed space 13 can be quantitatively determined according to the visual image of the sealed space 13, so that the detection efficiency and the accuracy of the detection result are improved, and more accurate data information is provided for solving the problem of water tightness.

In order to improve the water tightness detection capability, the heater 20 may be used to heat the container 10 to increase the temperature of the mixed liquid 11, thereby accelerating the mobility of the molecules of the mixed liquid 11. Further, the container 10 is a sealed container 10, and the pressure limiting valve 14 is arranged on the container 10, so that the pressure of the mixed liquid 11 can be increased, the testing capability of a limit test can be achieved, and the safety during the test can be ensured through the pressure limiting valve 14.

When the sealing device 12 is removed from the container 10, the mixed liquid 11 remains on the surface thereof. In order to prevent interference with the test result and improve the test efficiency, the mixed liquid 11 remaining on the surface of the sealing device 12 may be cleaned by using the cleaner 50. As an alternative embodiment, the cleaner 50 is a gas generator capable of providing high pressure gas for cleaning. It should be understood that the high pressure here is understood to mean that the gas has a higher pressure than the normal atmospheric pressure, and when released, has a jet phenomenon, so that the cleaning purpose can be achieved. The specific pressure can be set as required. For example, the high-pressure gas is compressed air of 0.1 to 1.0 MPa.

In summary, the detection method of the water tightness detection device provided by this embodiment is as follows:

firstly, a sealing device 12 is placed in a container 10, and a mixed liquid 11 immerses the sealing device 12;

immersion for a period of time during which the vessel 10 may be heated by the heater 20;

taking out the sealed device 12 and placing it on the inspection platform 60 for inspection;

before the sealing device 12 is opened, cleaning the residual mixed liquid 11 on the surface of the sealing device 12 by a cleaner 50;

opening the sealing device 12, and irradiating the sealed space 13 with ultraviolet rays using the ultraviolet light source 40;

the visual inspection unit 30 obtains a visual image of the sealed space 13 irradiated with the ultraviolet rays, and determines the water inlet area, and the size of the water droplets of the sealed space 13 according to the visual image.

The embodiment provides a water tightness detection device, not only can avoid the influence of human factor, improves the testing result accuracy, can realize automated production's automatic quantitative detection moreover, improves detection efficiency and provides more accurate data information for solving the water tightness problem.
